Surface transformations of platinum grains from Fifield, New South Wales, Australia by S.G. Campbell, F. Reith, B. Etschmann, J. Brugger, G. Martinez-Criado, R.A. Gordon and G. Southam (May–June, vol. 100, pages 1236–1243, 2015, Article DOI: http://dx.doi.org/10.2138/am-2015-4905; Errata DOI: http://dx.doi.org/10.2138/am-2015-E10077.

Tulameenite is tetragonal rather than cubic. Hence, the sentence “SEM micrographs show fine-grained, 150 nm cubic Pt-Cu minerals suggesting the presence of sub-micrometer tulameenite (PtFe0.5Cu0.5; based on their cubic structure and chemistry” should read “SEM micrographs show fine-grained, 150 nm isometric Pt-Cu minerals suggesting the presence of sub-micrometer tulameenite (PtFe0.5Cu0.5; based on the square-cross sections and qualitative chemistry”. Elsewhere in the text “cubic” should be read as “(pseudo-)cubic”.
